Mafunctioning instrument air regulator incident
Instrument technicians were re-calibrating a control valve positioner. The feedback arm between the valve and the positioner was
disconnected, a mA source was connected, and the valve was stroked using
the flapper & nozzle arrangement inside the positioner. While doing this, due to a faulty regulator, full instrument air pressure of 8.5 bar was applied and the top of the diaphragm casing ruptured propelling it far away. On investigation, inside the regulator, three screws had become loose in service due to vibration. The regulator did not have full rated relief and no
external relief device was fitted as part of the original valve supply.

Mobile Phone usage in restricted area inside control building

Also, you can find a very good explanation of minimum ignition energy (MIE) in the CCPS text "Guidelines for Determining the Probability of Ignition of a Released Flammable Mass". Although in this case it was generally agreed that cell phones present an extremely low risk as an ignition source, the company decided it was not worth the risk and upheld the rule to ban cell phone use in the plant.
In addition to the potential ignition source issues, the question of distractions always arises. Yet, at the same time, most organizations have so integrated cell phone use into their daily business that lack of access is a definite reduction in efficiency. The impossible (or at least very difficult) issue to address is how to allow normal company business while excluding needless distractions. Most organizations have some restrictions in place at least on paper.
1. distracter for operations: can you imagine an operator control panel working and talking on the phone at the same time? ¿Differentiating between sounds alarm signals and tones phone?
Simply because of the sensitivity of the operations control room, should minimize the factors which could cause distraction operators control panel. This is the main reason for the restriction.
2. Possibly the emission of signals or other cellular radios, instruments may alter operating wirelessly, which generate false signals and the problems that we know that these can generate.
3. The cell phone is not a certified electronic equipment for hazardous areas and remember that by the characteristics of the control room, they can be exposed to flammable gases and vapors, and cell element could be the initiator of an explosion or fire.
Happy day.
In unrated control rooms or break rooms - There are numerous other unrated electrical devices in these rooms, so they do not create an increased ignition risk. It is a management issue to make sure employees are not using them excessively, and that they do not carry them outside into the classified area.
